[0054] To make the above-mentioned objectives, features, and advantages of the embodiments of this application more apparent and understandable, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0055] As a specific embodiment of this application, such as Figures 1 to 4 As shown, this embodiment discloses an air conditioner 100, which may include a body 200, an air outlet duct, and at least one air supply duct 300.

[0056] The casing 200 may include a housing 210 and an evaporator 220, a condenser 230, a compressor 240 and a first fan 250 disposed within the housing 210.

[0057] The air duct 500 has an air inlet and an air outlet 510. The air duct 500 includes an air outlet surface with the air outlet 510 formed thereon. When the air duct 500 is installed at the target object 600 in the target space 400, the air outlet surface of the air duct 500 can form a continuous surface with the side wall surface 601 of the target object 600 located on one side of the air outlet 510. Alternatively, the air outlet surface of the air duct 500 can form a continuous surface with the side wall surfaces 601 of the target object 600 located on both sides of the air outlet 510. For example, the air outlet surface can seamlessly connect visually and physically with the side wall surface 601 of the target object 600 (such as a wall, ceiling, furniture, etc.), forming a smooth, integrated surface. This design, by concealing or integrating the edges of the air outlet surface and aligning it with the surrounding structure, enhances aesthetics and optimizes airflow distribution.

[0058] In the specific implementation process, the target space 400 can be an indoor space, and the target object 600 can be the corner of the vertical wall and ceiling of the room, or the corner of the side panel and top panel of a cabinet, etc. The air outlet duct can be installed at the corner. The air outlet surface of the air outlet duct 500 can be connected to the two surfaces of the corner, and the air outlet surface can be used as the decorative surface of the corner, so that the air outlet 510 can not be obtrusive to the wall surface or cabinet surface, and the air outlet duct 500 can be integrated with the wall or cabinet, thereby improving the aesthetics.

[0059] The air outlet 510 has an air outlet direction that is parallel to the side wall surface 601 of the target object 600 on at least one side of the air outlet surface, for reference. Figure 8 and Figure 18Of the airflow blown out from the air outlet 510, part of the airflow direction is parallel to the horizontal side wall surface 601 of the target object 600 (such as the ceiling of an indoor space), and the other part of the airflow direction is parallel to the vertical side wall surface 601 of the target object 600 (such as the vertical wall of an indoor space). In this way, discomfort caused to the human body by the airflow discharged from the air outlet 510 blowing directly on the human body can be avoided.

[0060] One end of each air supply duct 300 is connected to the body 200, and the other end extends to the target space 400. An air inlet duct 310 and a return air duct 320 are provided in the air supply duct 300. The air inlet duct 310 and the return air duct 320 are arranged side by side. The gas after heat exchange through the evaporator 220 is blown into the air inlet duct 310 by the first fan 250 and then flows into the target space 400. The gas in the target space 400 enters the housing 210 through the return air duct 320.

[0061] Specifically, the air conditioner 100 in this embodiment may include a body 200 and at least one air supply duct 300. The body 200 may include an evaporator 220, a condenser 230, a compressor 240, and a first fan 250. That is, the body 200 includes the components of the indoor and outdoor units of a conventional air conditioner 100. The air supply duct 300 in this embodiment, through the air inlet duct 310 and the air return duct 320, achieves the purpose of transporting the gas in the body 200 to the target space 400, and at the same time, returning the gas in the target space 400 back to the body 200. In other words, the air conditioner 100 in this embodiment places the evaporator 220, condenser 230, compressor 240 and fan of the traditional indoor and outdoor units in the same machine, and delivers gas to the target space 400 only through the air supply duct 300. This can effectively reduce the size of the indoor unit. At the same time, since there is only the air supply duct 300 and no other machines such as the evaporator 220 and fan in the indoor unit, the air conditioner 100 is quieter when blowing air in the target space 400, thus improving the user experience.

[0062] This application discloses a small-sized ducted air conditioner 100 with return air, which externalizes the core components of a traditional air conditioner 100, such as the heat exchanger, and delivers air through an air supply duct 300. In addition, the air supply duct 300 can be made into a small volume, thereby achieving integration into the home.

[0063] In addition, by setting the air outlet's airflow direction to be parallel to the side wall surface of the target object on at least one side of the air outlet, the airflow from the air outlet can be prevented from blowing directly onto the human body, thus improving human comfort.

[0064] As one example, such as Figure 5 and Figure 6As shown, in this embodiment, a body 200 can be equipped with one air supply duct 300. Of course, in other embodiments, a body 200 can be equipped with multiple air supply ducts 300.

[0065] More specifically, such as Figure 6 As shown, each air supply duct 300 may include a main pipe 330 and at least one branch pipe 340. One end of each branch pipe 340 is connected to the main pipe 330, and the other end is connected to the corresponding target space 400 to supply air to the target space 400.

[0066] When a unit 200 is equipped with one air supply duct 300, and there are multiple target spaces 400, a main pipe 330 and multiple branch pipes 340 can be used to supply air to different target spaces 400 (e.g., Figure 6 (As shown). When a unit 200 is paired with multiple air supply ducts 300, and there are many target spaces 400, each air supply duct 300 can include a main pipe 330, and is matched according to the number of target spaces 400 and the number of air supply ducts 300. Each air supply duct 300 can supply air to one of the target spaces 400 (e.g., ...). Figure 5 (As shown).

[0067] As another specific embodiment of this application, the air supply duct 300 of this embodiment may include a wall-penetrating section 350, which is used to pass through the cavity so that the end of the air supply duct 300 extends into the target space 400. The ratio of the cross-sectional area of ​​the wall-penetrating section 350 to the power of the air conditioner 100 is less than or equal to 57.37 cm2 / kw, wherein the cross-sectional area of ​​the wall-penetrating section 350 is less than or equal to 200 cm2.

[0068] Specifically, in this embodiment, the ratio of the cross-sectional area of ​​the wall-penetrating section 350 of the air supply duct 300 to the power of the air conditioner 100 is less than or equal to 57.37 cm² / kW. For example, in this embodiment, when the power of the air conditioner 100 in the wall-penetrating section 350 is 1.5 horsepower or higher, the upper limit of the cross-sectional area of ​​the corresponding wall-penetrating section 350 is 200 cm². When the power of the air conditioner 100 is lower, the cross-sectional area of ​​its wall-penetrating section 350 can be even smaller. Specifically, the ratio of the cross-sectional area to the power of the wall-penetrating section 350 of the air supply duct 300 in this embodiment is designed because, on the one hand, power has a significant limitation on the cross-sectional area; the cross-sectional area of ​​the air supply duct 300 at a certain power is fixed. On the other hand, it is subject to existing laws and regulations, and the cross-sectional area cannot be infinitely large.

[0069] Specifically, the cross-sectional shape of the wall-penetrating section 350 in this embodiment can be circular, square, or other shapes. Furthermore, most general wall-penetrating holes are circular; therefore, the wall-penetrating section 350 in this embodiment is preferably circular. Preferably, the shape of the wall-penetrating section 350 of the air conditioner 100 in this embodiment is circular, and the cross-sectional area of ​​the wall-penetrating section 350 is less than or equal to 200 cm², that is, the diameter is less than or equal to 160 mm.

[0070] Specifically, in this embodiment, each air supply duct 300 needs to pass through the wall to enter the target space 400. Therefore, each air supply duct 300 in this embodiment may include a wall-penetrating section 350. In this embodiment, the wall-penetrating section 350 may be circular, and its diameter is less than or equal to 160mm. Furthermore, the diameter of the wall-penetrating section is designed to match the power of the air conditioner 100, which is greater than 1.5 horsepower. In this way, the power requirements of the air conditioner 100 are met, while also satisfying the requirement that the wall-penetrating hole cannot be too large.

[0071] As a specific embodiment of this application, such as Figures 7-10 As shown, each main pipe 330 and branch pipe 340 in this embodiment may include a pipe body 360 and a first partition 370. The first partition 370, located inside the pipe body 360, extends in a direction parallel to the extension direction of the pipe body 360, dividing the pipe body 360 into an air inlet duct 310 and a return air duct 320.

[0072] More specifically, in this embodiment, the cross-sectional areas of the air inlet duct 310 and the air return duct 320 are the same. This ensures that the air volume of the air inlet and the air return is equivalent.

[0073] When the air supply duct 300 includes a main pipe 330 and a branch pipe 340, the air inlet duct 310 of the main pipe 330 and the air inlet duct 310 of the branch pipe 340 are connected, and the return air duct 320 of the main pipe 330 and the return air duct 320 of the branch pipe 340 are connected.

[0074] Specifically, when the air supply duct 300 in this embodiment includes a main pipe 330 and a branch pipe 340, the wall penetration section 350 is located at the branch pipe 340.

[0075] More specifically, in this embodiment, the cross-section of the air supply duct 300 at the wall penetration section 350 can be designed as circular, while the ducts at other locations can be designed as circular (e.g., Figure 9 (as shown) or other shapes. For example, the pipe between the through-wall section 350 and the fuselage 200 can be designed as square, such as rectangular (as shown). Figure 10 (As shown) or square. This design makes the air supply duct 300 more aesthetically pleasing and easier to install when it is outside the wall, and it also better matches the wall penetration hole in the wall penetration section 350.

[0076] As a specific embodiment of this application, the air supply duct 300 in this embodiment is provided with a heat insulation layer (not shown in the figure) on its wall. The heat insulation layer can keep the gas inside the air supply duct 300 warm and isolate it from the ambient temperature, reducing the influence of the external environment on the temperature of the transported gas during the transport process.

[0077] As a specific embodiment of this application, such as Figure 9 and Figure 10 As shown, the air supply duct 300 in this embodiment is formed by one or more duct units 380. When the air supply duct 300 is formed by connecting multiple duct units 380 together, the multiple duct units 380 are interlocked to form the entire duct. Specifically, a retaining ring 390 is provided at the connection position between the duct units 380 (e.g., Figure 9 As shown), the retaining ring 390 snaps the ends of the pipe units 380 on both sides together and seals them.

[0078] As a specific embodiment of this application, such as Figure 11 and Figure 12 As shown, each air supply duct 300 in this embodiment is provided with an air outlet duct 500 at its end, which is connected to the air inlet duct 310. The extension direction of the air outlet duct 500 is parallel to the air outlet direction of the air inlet duct 310. An air outlet 510 is provided at the air outlet duct 500. The gas in the air inlet duct 310 flows into the air outlet duct 500 and is blown out from the air outlet 510.

[0079] Specifically, in this embodiment, an air outlet duct 500 is provided at the end of the air supply duct 300. When the gas is delivered to the target space 400 by the air supply duct 300, it is then blown out through the air outlet duct 500. The position and direction of the gas flow can be controlled by the air outlet duct 500.

[0080] Specifically, in this embodiment, the direction in which the air outlet duct 500 extends is parallel to the direction of air outlet, which can minimize the loss of gas energy.

[0081] In addition, the cross-sectional area of ​​the outlet duct 500 in this embodiment is larger than the cross-sectional area of ​​the end of the supply duct 300, so as to avoid gas energy loss and turbulence.

[0082] Specifically, in this embodiment, the air outlet 510 is located on the side wall of the air outlet duct 500, which is parallel to the extension direction. This ensures that the direction of the final blown gas is perpendicular to the extension direction of the air outlet duct 500.

[0083] Of course, in other embodiments, the air outlet 510 and the air outlet direction can be adaptively adjusted to meet different air outlet requirements.

[0084] Specifically, when the air supply duct 300 includes a main pipe 330 and a branch pipe 340, each branch pipe 340 that delivers air to the target space 400 is connected to an air outlet duct 500 at its end.

[0085] As a specific embodiment of this application, such as Figure 13-16 As shown, in this embodiment, the air outlet duct 500 is provided with at least one first baffle 520 that is substantially perpendicular to the extending direction of the air outlet duct 500. Each first baffle 520 is provided with at least one first through hole 521. At least part of the gas in the air outlet duct 500 passes through the first through hole 521 of the first baffle 520 and is then blown out from the air outlet 510.

[0086] Specifically, in this embodiment, at least one first baffle 520 is provided inside the air outlet duct 500 to block the gas inside the air outlet duct 500, thereby preventing most or almost all of the gas inside the air outlet duct 500 from being blown to the end of the air outlet duct 500 and then blown out from the air outlet 510, thus avoiding uneven air outlet.

[0087] Preferably, in this embodiment, a plurality of first baffles 520 are provided inside the air outlet duct 500, and the plurality of first baffles 520 are arranged at intervals along the extension direction of the air outlet duct 500.

[0088] Specifically, by setting multiple first baffles 520 inside the air outlet duct 500 along its extension direction, the air volume blown out from the air outlet 510 can be further optimized, thereby further improving the uniformity of the airflow.

[0089] As a specific embodiment of this application, at least a portion of the outer periphery of the first baffle 520 is in contact with the inner wall of the air outlet duct 500, thus ensuring that all the gas flowing through the first baffle 520 passes through the first through hole 521 of the first baffle 520 before flowing to the rear.

[0090] Specifically, the outer periphery of each first baffle 520 contacts the side wall of the air outlet duct 500 where the non-air outlet is located.

[0091] Specifically, the cross-sectional shape of the first through hole 521 in this embodiment can be circular, elliptical, square, or other shapes. Preferably, the shape of the first through hole 521 in this embodiment is circular.

[0092] Preferably, all the first baffles 520 in this embodiment are arranged in parallel to each other.

[0093] Preferably, in this embodiment, all the first baffles 520 are perpendicular to the extension direction of the air outlet duct 500, and the shape of all the first baffles 520 is consistent with the cross-sectional shape of the side wall of the air outlet duct 500.

[0094] Specifically, in this embodiment, the cross-sectional shape of the air outlet duct 500 is triangular, and the cross-sectional shape of the first baffle 520 is also triangular.

[0095] As a specific embodiment of this application, the proportion of the cross-section of the first through hole 521 of the first baffle 520 to the total cross-sectional area of ​​the first baffle 520 gradually increases from the position of the air inlet duct 310 to the position away from the air inlet duct 310.

[0096] Specifically, since the wind speed is higher near the air inlet duct 310 and lower far from the air inlet duct 310, this design ensures that the wind speed of the gas blown out by the air outlet duct 500 is similar near the air inlet duct 310 and far from the air inlet duct 310, resulting in good uniformity of the blown gas and improving the user experience.

[0097] Specifically, the cross-sectional area of ​​the first through hole 521 of the first baffle 520 in this embodiment can be changed by changing the number of first through holes 521 or by changing the cross-sectional area of ​​each first through hole 521.

[0098] As a specific embodiment of this application, the density of the first baffle 520 in this embodiment gradually decreases in the direction from the position close to the air inlet duct 310 to the position far away from the air inlet duct 310.

[0099] Specifically, in this embodiment, the density of the first baffles 520 near the air inlet duct 310 is set to be large, while the density of the first baffles 520 far from the air inlet duct 310 is set to be small. This makes the airflow near the air inlet duct 310 and the airflow far from the air inlet duct 310 have similar speeds, thereby making the uniformity of the gas blown out of the air outlet 510 good.

[0100] As a specific embodiment, the density of the first baffle 520 set at the air outlet duct 500 and the cross-sectional area of ​​the first through hole 521 at the first baffle 520 can be designed according to the situation, so that the uniformity of the gas blown out of the air outlet 510 of the air outlet duct 500 is good.

[0101] More specifically, the diameter of the first through hole 521 at the first baffle 520 in this embodiment is adjustable. By changing the total cross-section of the first through hole 521 at each first baffle 520, the ratio of the total cross-sectional area of ​​the first through hole 521 to the cross-section of the first baffle 520 can be changed, thereby further improving the uniformity of the air output.

[0102] In another embodiment, the first baffle 520 of this embodiment can be set with different areas at different distances from the air inlet duct 310, so as to further increase the uniformity of the air outlet.

[0103] As a specific embodiment of this application, such as Figure 13-16 As shown, in this embodiment, a second baffle 530 is provided at the air outlet 510 of the air outlet duct 500. The second baffle 530 is provided with at least one second through hole 531, through which the gas from the air outlet duct 500 is blown out.

[0104] Specifically, in this embodiment, a first through hole 521 of a first baffle 520 is provided at the air outlet duct 500, and a second baffle 530 is provided at the air outlet 510, with a second through hole 531 provided at the second baffle 530, to further increase the uniformity of air outlet from the air outlet duct 500.

[0105] As a specific embodiment of this application, a third baffle 540 is also provided at the air outlet 510 of the air outlet duct 500 in this embodiment. The third baffle 540 is located outside the second baffle 530 so that the gas blown out from the second baffle 530 passes through the third baffle 540 and is then blown out.

[0106] Specifically, in this embodiment, the gas blown out from the second baffle 530 passes through the third baffle 540 before being blown out again, further improving the uniformity of the airflow.

[0107] Specifically, the third baffle 540 in this embodiment can be designed as a filter structure (e.g. Figure 11 and 12 As shown), the filter structure of this embodiment can be obtained by setting a filter screen in the center of the frame structure. As another specific embodiment, the third baffle 540 of this embodiment can be designed as a horizontal strip-shaped grid structure (e.g., Figure 13 and Figure 14 As shown), the direction of airflow can be adjusted by changing the number and direction of the grid structure. As another specific embodiment, the third baffle 540 of this embodiment can also be designed as a perforated partition structure (e.g., Figure 15 and Figure 16 As shown in the figure, the size and distribution of the holes on the partition can be designed according to actual conditions. Specifically, in this embodiment, the holes on the partition have a larger diameter in the middle and smaller diameters on both sides.

[0108] Specifically, in this embodiment, a first baffle 520, a second baffle 530, and a third baffle 540 are provided at the air outlet duct 500. The three components achieve three-level uniform airflow, resulting in good uniformity of the gas blown out from the air outlet duct 500 and almost no wind sensation, thus improving the user experience.

[0109] As a specific embodiment of this application, such as Figure 17 and Figure 18 As shown, the air outlet duct 500 of this embodiment is also provided with a baffle plate 550 and air guiding mechanisms 560 on both sides of the baffle plate 550 at the air outlet 510. The baffle plate 550 can be parallel to the air outlet surface. The baffle plate 550 can divide the air outlet 510 into two air outlet areas on both sides of the baffle plate 550. The air outlet direction of each air outlet area is parallel to the side wall surface of the target object on the same side. In this way, the airflow at the air outlet 510 can be blown out in two mutual directions, which is beneficial to improving the diffusion efficiency of the airflow in the target space.

[0110] The air guide mechanism 560 directs the air blown out of the air outlet 510 toward the side away from the wind deflector 550.

[0111] Specifically, in this embodiment, a baffle plate 550 and a guide mechanism 560 are provided at the air outlet 510 of the air outlet duct 500. The baffle plate 550 is located in the middle of the air outlet 510, while the guide mechanism 560 guides the air blown out of the air outlet 510 to a position away from the middle, thereby preventing the air in the air blown out of the air outlet 510 from blowing directly at the user, thereby improving the user experience.

[0112] Specifically, in this embodiment, the air guide mechanism 560 can be rotatably connected to the wall of the air outlet duct 500, thereby controlling the direction of the gas blown out from the air guide mechanism 560 by controlling the rotation of the air guide mechanism 560.

[0113] Specifically, the air guiding mechanism 560 in this embodiment may include multiple parallel air guiding blades, each of which can rotate. The multiple air guiding blades can rotate individually or in conjunction with each other.

[0114] As a specific embodiment of this application, such as Figure 11 As shown, the air outlet duct 500 of this embodiment may include multiple interconnected and communicating air outlet modules 501. Adjacent air outlet modules 501 are snap-fitted together. Each air outlet module 501 may have a first baffle 520 extending vertically. A second baffle 530 and a third baffle 540 are provided at the air outlet 510 of each air outlet module 501. A baffle plate 550 and an air guide mechanism 560 are also provided at the air outlet 510 of each air outlet module 501.

[0115] As a specific embodiment of this application, such as Figure 19As shown in Figure 20, the air outlet duct 500 of this embodiment may further include a sidewall 570, which is installed on the target object 600 to be installed, so that the air outlet duct 500 exposes the surface where the air outlet 510 is located when installed on the target object. Furthermore, the plane where the air outlet 510 is located forms a continuous surface with the sidewall surface 601 of the target object 600 located on at least one side of the air outlet 510.

[0116] Specifically, the target object in this embodiment can be a specific object in the target space 400, such as a room or a cabinet. As one embodiment, when the air duct 500 is installed on the target object, the air outlet 510 of the air duct 500 is exposed, and the plane containing the air outlet 510 forms a continuous surface with the side wall surface 601 of the target object 600 located on at least one side of the air outlet 510 (e.g., ...). Figure 19 , Figure 21 and Figure 22 As shown, this makes the exhaust duct 500 and the target object 600 look harmonious from the outside, thus making the exhaust duct 500 look beautiful when installed on the target object 600.

[0117] Specifically, in this embodiment, the plane where the air outlet 510 of the air outlet duct 500 is located can form a substantially continuous surface with the exposed surface 601 of the target object 600 located on one side of the air outlet 510.

[0118] For example, when the cross-section of the air outlet duct 500 is triangular (e.g.) Figure 19 As shown), when the target object is the interior wall of the room, it can be set at the position between the top and the side wall of the room, with only the air outlet 510 exposed. The plane where the air outlet 510 is located forms a continuous zigzag surface with the surface of the ceiling and the side wall.

[0119] When the cross-section of the 500mm exhaust duct is quadrilateral, such as Figure 20 Two of the sides can be installed on the top and side wall of the target object 600, while the other two sides can have an air outlet 510 set in one place or both places.

[0120] Preferably, when the cross-section of the air outlet duct 500 is quadrilateral, such as... Figure 21 and Figure 22 As shown, the plane where the air outlet 510 is located and the side wall surface 601 of the target object 600 located around the air outlet 510 form a basically continuous surface.

[0121] More preferably, such as Figure 22As shown, in this embodiment, the plane where the air outlet 510 is located is on the same plane as the side wall surface 601 of the target object 600 near the air outlet 510. At this time, it is necessary to open an installation groove at the target object 600 and embed the air outlet duct 500 into the installation groove, with only the air outlet surface 502 or the air outlet 510 exposed.

[0122] More specifically, the continuity described in this embodiment does not mean that the air outlet or air outlet surface and the outside of the side wall must be strictly on the same plane, curved surface, or folded surface. When the air outlet 510 or air outlet surface 502 protrudes or is recessed within an area of ​​about 1-2 cm outside the side wall, it can also be regarded as a continuous surface or the same plane.

[0123] As a specific embodiment of this application, such as Figure 23 and Figure 24 As shown, an installation structure is provided at the side wall 570 of the air outlet duct 500 in this embodiment. The installation structure may include a magnetic structure or a snap-fit ​​structure to attract or snap with the mounting bracket 580 at the target object 600, thereby allowing the air outlet duct 500 to be installed at the target object 600. Specifically, one mounting bracket 580 can install one air outlet module 501, or multiple air outlet modules 501.

[0124] Specifically, such as Figure 24 As shown, in this embodiment, a mounting bracket 580 is provided with a snap-fit ​​structure 581, and a corresponding structure is provided on the side wall 570 of the air outlet duct 500 to engage with the snap-fit ​​structure 581. When installing the air outlet duct 500, the mounting bracket 580 can be first fixed to the target object 600, and then the air outlet duct 500 can be snapped into the snap-fit ​​structure 581 of the mounting bracket 580. In this embodiment, the mounting bracket 580 can simultaneously mount two air outlet modules 501.

[0125] Of course, as in other embodiments, the connection between the mounting bracket 580 and the mounting structure can be in other forms such as snap-fit. The air outlet duct 500 cooperates with the mounting bracket 580 on the target object 600, so that the air outlet duct 500 can be quickly and flexibly installed on the target object 600.

[0126] As a specific embodiment of this application, the cross-section of the air outlet duct 500 is a right-angled triangle, with the hypotenuse being the outlet surface and the two right-angled sides being the mounting or contact surfaces. The two right-angled sides are respectively attached to the top and side walls of the room (i.e., the target object), with only the surface containing the air outlet 510 exposed. Mounting components can also be installed on the right-angled sides for installation on the top and / or side walls.

[0127] More specifically, each mounting bracket 580 in this embodiment may include a connecting portion 582 and a mounting portion 583. The connecting portion 582 connects the mounting portion 583 and connects the mounting bracket 580 to the target object 600 via the connecting portion 582. The mounting portion 583 cooperates with the mounting structure to connect the air outlet duct 500 to the mounting bracket 580.

[0128] As a specific embodiment of this application, such as Figure 25 and Figure 26 As shown, the housing 210 of this embodiment may include a second partition 260, which divides the housing 210 into a first receiving cavity 211 located above and a second receiving cavity 212 located below. The evaporator 220 and the first fan 250 are located in the first receiving cavity 211, and the condenser 230 is located in the second receiving cavity 212.

[0129] Specifically, in this embodiment, the housing 200 can be provided with a second partition 260, which divides the housing 210 into two receiving cavities. These two cavities are respectively equipped with an evaporator 220 and a condenser 230. In this embodiment, the evaporator 220 is located in the upper first receiving cavity 211, which is connected to the air supply duct 300. This allows gas to exchange heat through the evaporator 220 before flowing out through the air supply duct 300 into the target space 400. The condenser 230, located in the second receiving cavity 212, exchanges heat with the liquid in the evaporator 220, ensuring the evaporator 220 reaches a suitable heat exchange temperature. The second partition 260 also prevents gas from passing through both the space containing the evaporator 220 and the space containing the condenser 230, thus avoiding any impact on the heat exchange effect.

[0130] More specifically, in this embodiment, at least one third through hole (not shown in the figure) is provided at the second partition 260, and the third through hole is located at a position corresponding to the location of the condenser 230. Specifically, since condensate easily forms in the evaporator 220 when exchanging heat with the gas, the condensate will flow down the evaporator 220 and drip below. A drip tray can be provided below the evaporator 220, or the second partition 260 can serve as the drip tray. In this embodiment, the third through hole at the second partition 260 allows the condensate to drip down along the third through hole. Since the third through hole is located above the condenser 230, the condensate directly drips onto the condenser 230, thereby cooling the condenser 230 and improving the overall energy efficiency of the unit.

[0131] In another specific embodiment of this application, the second partition 260 is inclined, and the second partition 260 is inclined toward the side where the condenser 230 is located. Specifically, the second partition 260 in this embodiment can be set at an inclination angle, so that the condensate can flow along the second partition 260 to one side and eventually drip onto the condenser 230, thereby cooling the condenser 230 and improving the overall energy efficiency of the unit.

[0132] As a specific embodiment of this application, the housing 210 of this embodiment may further include a third partition 270 disposed in the first receiving cavity 211. The third partition 270 divides the first receiving cavity 211 into a first sub-cavity 213 and a second sub-cavity 214. An evaporator 220 is disposed in the first sub-cavity 213, and a first fan 250 is disposed in the second sub-cavity 214. An air inlet duct 310 is connected to the second sub-cavity 214, and a return air duct 320 is connected to the first sub-cavity 213. A fourth through hole 271 is provided at the third partition 270 so that the air flowing into the first sub-cavity 213 from the return air duct 320 is heat-exchanged by the evaporator 220 and then flows to the second sub-cavity 214 through the fourth through hole 271. The first fan 250 then blows the gas into the air inlet duct 310.

[0133] Specifically, in this embodiment, the first receiving cavity 211 is divided into a first sub-cavity 213 and a second sub-cavity 214 by a third partition 270. This allows the inlet of the air inlet duct 310 to be connected to the second sub-cavity 214, while the outlet of the return air duct 320 is connected to the first sub-cavity 213. This separates the exhaust gas from the return gas, preventing gas from flowing into the air inlet duct 310 without heat exchange, which would affect the exhaust temperature.

[0134] Furthermore, in this embodiment, a fourth through hole 271 is provided at the third partition 270, and the first fan 250 can be a centrifugal fan. The air inlet of the centrifugal fan is located at the fourth through hole 271, and the air outlet 510 of the centrifugal fan can be directly connected to the inlet of the air inlet duct 310, directly blowing the gas in the first sub-cavity 213 into the air inlet duct 310.

[0135] More specifically, in this embodiment, a fresh air inlet (not shown in the figure) is provided on the side wall of the first receiving cavity 211, and a fresh air valve (not shown in the figure) is provided at the fresh air inlet so that when the fresh air valve is opened, the first fan 250 blows part of the gas flowing from the first sub-cavity 213 into the second sub-cavity 214 and part of the fresh air entering from the fresh air inlet into the air intake duct 310.

[0136] Specifically, in this embodiment, a fresh air inlet is provided on the side wall of the first receiving cavity 211. When the centrifugal fan blows the gas from the first sub-cavity 213 into the air inlet duct 310, due to the negative pressure, outside air will enter the second sub-cavity 214 through the fresh air inlet and then be blown into the air inlet duct 310 by the centrifugal fan.

[0137] Specifically, a fresh air valve is installed at the fresh air inlet. When the temperature difference between indoors and outdoors is small, the fresh air valve can be opened, so that the fresh air and the gas in the first sub-cavity 213 are blown into the air intake duct 310 and then into the target space 400. When the temperature difference between indoors and outdoors is large, the fresh air valve can be closed, and only the gas in the first sub-cavity 213 is blown into the target space 400.

[0138] Specifically, in this embodiment, the fresh air inlet and fresh air valve can be located on the side wall of the first sub-cavity 213 or on the side wall of the second sub-cavity 214. Preferably, the fresh air inlet and fresh air valve are located on the side wall of the first sub-cavity 213, so that the fresh air can pass through the evaporator 220 together with the gas flowing in through the return air duct 320 for heat exchange before being blown into the air inlet duct 310 by the centrifugal fan.

[0139] As a specific embodiment of this application, the second receiving cavity 212 may further include a fourth partition 280, which divides the second receiving cavity 212 into a third sub-cavity 215 and a fourth sub-cavity 216. The condenser 230 is located in the third sub-cavity 215, and the compressor 240 is located in the fourth sub-cavity 216. The third sub-cavity 215 may further include a second motor (not shown in the figure) and a second fan 290. The second motor drives the second fan 290 to rotate to dissipate heat from the condenser 230. The second motor drives the second fan 290 to rotate, and the second fan 290 carries away heat from the condenser 230 during rotation, preventing the condenser 230 from overheating.

[0140] As a specific embodiment of this application, at least one side wall of the third sub-cavity 215 is provided with an air outlet 217, and a grille 218 is provided at the air outlet 217. The condenser 230 is arranged around the side wall of the third sub-cavity 215, which does not have an air outlet. Specifically, the grille 218 in this embodiment can, on the one hand, prevent external dust from entering the second receiving cavity 212, and on the other hand, protect the outside world from harming personnel caused by the fan.

[0141] Specifically, the second fan 290 in this embodiment can be an axial flow fan.

[0142] As a specific embodiment of this application, the air intake volume of the perforated air supply duct 300 in this embodiment is 650m³. 3 / h-11000m 3 / h. For example, the intake air volume can be 650 m³ / h. 3 / h, 700m 3 / h, 750m 3 / h、800m 3 / h, 900m3 / h, 1000m 3 / h or 1100m 3 / h etc.

[0143] Specifically, when the fresh air valve in this embodiment is closed, and the entire system is in internal circulation, and the wall-penetrating section 350 of the air intake duct is limited to a diameter of 160mm, the air intake volume in this embodiment can reach 650m³ / h. 3 / h~700m 3 / h. When the fresh air valve in this embodiment is opened, combined with the internal circulation and external fresh air, the air intake volume of the air intake duct in this embodiment can reach 1100m³ / h. 3 / h or even higher. Specifically, the intake air volume is related to the diameter of the 300mm supply duct and the power of the centrifugal fan. Of course, the size of the fresh air inlet will also have a certain impact on the intake air volume.
